最近看到一组照片,是高动态范围成像(High Dynamic Range Imaging,简称HDRI或HDR)相机照的,和普通的照片确实很不一样,转来给大家瞧瞧。一般的相机如果拍反差很大的外景,亮的地方就会比较亮,暗的地方会比较暗,不能兼顾。但是这种HDR相机,可以同时用几种曝光效果来取景,即亮的地方少曝光,暗的地方多曝光,这样合成起来的照片就会全局都很清楚。理论上说,如果相片的清晰度足够高,用软件来增加减少亮度,也可以达到比较类似的效果。不过这种相片看上去不真实,譬如天上的云是暗的,并不反映人们的视觉效果。

有些照片看着怪怪的,譬如最后一张,天是黑沉沉的,虽然水中有着清晰的倒影,但是看不出来那水是清澈的还是浑浊的,因为水也是黑沉沉的,。。
同感:)
哪怕是本来该热闹的地方,也变得黑沉沉的了。。:)
嗯,不过也许是我们还不习惯,或者这个技术还需要改进,
